Slowness

Jump to navigation Jump to search

If anyone is noticing Robowiki being slow, it's because a PHP process is hitting a cpu bottleneck right now.

The logs are showing Bing and Baidu doing some heavy spidering right now so it could be that... but it could be something else, I'm not 100% sure.

Are you using php-fpm or spawn-fcgi? From my test, the former performs better under heavy load (though I am not sure since I tested it with nginx, not lighttpd; tested with apachebench with wordpress installation)

fcgi, however the number of requests per second was fairly modest really, so I doubt that type of overhead was the issue. More likely something on the MediaWiki side was being inefficient on the particular pages being spidered I think.

Yay for speedups! :D

I did some tweaking to the server configuration... according to benchmarks I improved things so that Main_Page went from 5.41 requests/second, all the way up to 80.71 requests/second.

Special:RecentChanges improved less though, going from 2.26 requests/second to 3.44 requests/second.
